The MK 18 “D” & “C” Sports Racing Car Kits

The new LeGrand Mk 18 Sports Racing Car is the newest and most unique lightweight sports racing car available today. The car was designed to use any of the new multi-cylinder motorcycle engines such as the Kawasaki Z-1 (900cc), Honda 750, and Suzuki 750 water cooled. These engines are ideally suited to sports racing use since they are lightweight, are very powerful, and are readily available. In addition, there is a great deal of performance equipment available including turbosuperchargers.

The new LeGrand Mk 18 will be suitable for either D or C-SR depending on engine type used. An Mk 18 with Kawasaki Z-1 4-cylinder engine weighs 640 pounds track ready, which is 200 to 300 pounds lighter than most D-SR’s now running. The lightweight was achieved by a total design concept of reducing the size and weight of all components to a minimum and to utilize fully the lightweight and compact size of the motorcycle engine/transmission package. For example:

·  The wheelbase is very short at only 76 inches.

·  A revolutionary steering set-up reduces steering system weight by 50%.

·  A special rear drive hub incorporates the drives sprocket as well as a single disc brake.

·  Special Koni coil spring/shock units are half the weight of usual units.

LeGrand offers the Mk 18 mainly in kit form, although complete cars can be supplied on request. We emphasize our kits because it reduces our costs and allows the buyer to obtain the best engineered car available at a reasonable price. In addition, those who choose to assemble their own car will learn a great deal about race car design and construction, and they can take a great deal more pride in their car once it has been completed. LeGrand has been building “assemble-it-yourself” race cars since 1962, and this long experience in supplying kits allows us to offer the easiest to assemble kit available.
